The sxpm program
can be used to view any XPM (version 1, 2, or 3) file and/or to convert
a file from XPM1 or XPM2 to XPM version 3. If sxpm is run with any dummy
option specified, the usage is displayed. If no geometry is specified, the
show window will have the size of the read pixmap. Pressing the key Q in
the window will quit the program.
